Alternatives are meant for something else. I could want to run a small
HTML viewer when I get a HTML-encoded mail, but could want to run
mozilla or konqueror as my 'default' webbrowser, when an other
application tries to run one. Yes, you could create /another/
alternative for /every/ MIME type in your mailcap, but that would bloat
the alternatives system.

Also, going the alternatives way would result in a *lot* of work (you'd
have to remove all other mailcap entries, since they'd conflict with
your work), and would not really be an improvement, since only the
sysadmin could change preferences, and users would still be where they
are today: having to copy lines from /etc/mailcap to ~/.mailcap.

Worse; now they can copy lines; then, they'd have to edit them to be
useful, else they'd /still/ run the sysadmin's preferences.

Alternatives and mailcap are two different worlds. Please keep them

It's done in there, all over the place! There's a 'test' option, which
is meant to use a line conditionally; it's commonly used to test whether
$DISPLAY is set, which is *exactly* what you need.
